Hubei New Desheng Material Technology Co., Ltd. is a professional manufacturer of raw materials for biological buffer.The biological buffer produced by our company are stable with high purity.It can be used in common skin care products and cosmetics such as toner, essence, lotion, eye cream and face cream middle. Here are three buffers commonly used in cosmetic raw materials, 3(-hydroxymethyl)aminomethane (Tris), 4-hydroxyethylpiperazineethanesulfonic acid (HEPES),and bis(2-hydroxyethyl)idene Amino tris (hydroxymethyl) methane (Bis-Tris).
TRIS
3(-Hydroxymethyl)aminomethane (TRIS), also known as tromethamine, is a zwitterionic biological buffer. In the PH range of 7.2-9.0, TRIS has the best buffering ability, and can maintain the PH value of the solution for a period of time at 4.75-5.75 that is just suitable for human skin. Therefore, TRIS buffers are often used in emulsifiers, thickeners, moisturizers and other formulations to adjust and stabilize the acidity and alkalinity of products. Because TRIS buffers can reduce or suppress products’ odor, they can be used in the formulation of sunscreens, leave-in nail polishes, eye makeup and lotions.
HEPES
Like TRIS, 4-Hydroxyethylpiperazineethanesulfonic acid (HEPES) is also a zwitterionic buffer with a suitable pH range of 6.8-8.2. HEPES buffer is often used to adjust the PH value of cosmetic products, stabilize it in a weakly acidic state that is suitable for human skin.It does not affect the efficacy of other ingredients, and even promotes the transdermal absorption of its functional ingredients. The concentration of the buffer affects its buffering capability,a certain concentration of HEPES can be used in exfoliating products.
Bis-Tris
Bis (2-hydroxyethyl) imino tris (hydroxymethyl) methane (Bis-Tris) is a weakly acidic buffer containing trace ionized hydrogen ions. In raw materials of cosmetics, Bis-Tris can adjust the PH value of the product and keep it stable in a suitable acid state. Bis-tris buffer has excellent decontamination, dispersing, emulsifying, anti-static ability, and high ultraviolet absorption ability, so it is often used to replace maleic acid in some sunscreens.
The TRIS, HEPES and BIS-TRIS produced by our company are white crystalline powder with excellent properties.The purity can reach more than 99%. Professional R&D team can customize indicators according to your requirements, welcome to consult.
